Types of Scaffoldings

The type of flooring could make a significant difference in the appearance and finishing of your

project. Good looking flooring could enhance the value of the home and could possibly attract
new customers. The most popular flooring types from which to choose are:-

1. Standard Tabular Frame Scaf-

folds

This is the most frequently used

scaffold in construction. Historically
it has been made of steel tubing,

but aluminum is gaining popularity.
The scaffold is manufactured in var-
ious configurations and spans. On

some systems, ladder rungs are
built into the end frames as shown

in fig. These ladders are not suita-
ble for tall scaffold towers unless

rest platforms are installed at regu-
lar intervals and trapdoors are provided in the platforms. Again this ladder is not suitable for high

scaffolds. Scaffolds in excess of 9 meters (30 feet) should have built-in stairs with rest platforms.
Vertical ladders can reach up to 9 meters, but above 2.2 meters (7 feet) they require a safety
cage.

The advantages of the frame scaffold are that it is simple to assemble, many construction trades
are familiar with its use, and the components can be lifted manually by workers. However, as with

other systems, all parts must be used. Failure to install any of the components, such as bracing
and base plates, may lead to accidents.

Types of Frame scaffolds:

Standard walk-through frame scaffold (E.g.- L.D

Tower, H.D. Tower):- This is a variation of the standard
tubular frame scaffold. Although primarily designed to

accommodate pedestrian traffic at the ground or street
level, the walk-through scaffold is frequently used by

the masonry trade to provide greater height per tier and
easier distribution of materials on platforms at interme-

diate levels.
